Species tulips refers to those varieties which have not been bred or hybridised and remain essentially as they are found in nature. Botanical tulips are hybrids, but hybrids which remain very close to the original species. Neither of these terms refers to “wild” tulips. All tulips sold by the Dutch, including the species and botanical tulips, are actually propagated and grown in Holland. Species and botanical tulips are generally smaller than other tulips. They are especially prized for growing in rock gardens.
